- "This module describes a YANG model for BGP protocol
- configuration.It is a limited subset of all of the configuration
- parameters available in the variety of vendor implementations,
- hence it is expected that it would be augmented with vendor-
- specific configuration data as needed.Additional modules or
- submodules to handle other aspects of BGP configuration,
- including policy, VRFs, VPNs, and additional address families
- are also expected.
-
- This model supports the following BGP configuration level
- hierarchy:
-
- BGP
- |
- +-> [ global BGP configuration ]
- +-> AFI / SAFI (address family)
- +-> [AFI-specific config ]
- +-> peer group
- +-> [ peer group config ]
- +-> AFI / SAFI [ per-AFI overrides ]
- +-> neighbor
- +-> [ per-neighbor overrides ]
- +-> AFI / SAFI [ per-AFI overrides ]
- +-> neighbor
- +-> [ neighbor config ]
- +-> AFI / SAFI [ per-AFI overrides ]";
